The KNX Raspberry Pi HAT and the Raspberry Pi itself need to be supplied separately. Both are functionally isolated from each other by the ISO7741. The HAT is supplied through the KNX bus. On the top left of the shield, there are two 1 mm terminal pins to connect the bus. Normally a red/grey Wago connector is used to plug onto these pins.

RASPBERRY PI® KNX INTERFACE
The KNX Raspberry Pi HAT and the Raspberry Pi itself need to be supplied separately. Both are functionally isolated from each other by the ISO7741. The HAT is supplied through the KNX bus. On the top left of the shield, there are two 1 mm terminal pins to connect the bus. Normally a red/grey Wago connector is used to plug onto these pins. The Hardware. 3 components are needed: A Raspberry PI. A EIB Buscoupling Unit. Adapter Board to connecting both. You can use A or the B Model of Raspberry Pi. The eibd daemon has minimal hardware requirements. There are two possibilities for connecting a computer to the EIB/KNX Bus over a RS232 serial interface. While designed primarily for the Raspberry Pi family of single-board computers, the KNX HAT boasts impressive compatibility: In its default mode the board has been confirmed as working with the Raspberry Pi, Odroid C2 and C4, Rock Pi 4, Asus TinkerBoard S, Libre Le Potato, and Banana Pi M4 and M5, while a jumper allows it to be altered to work with the NanoPi M4 as well. The KNX bus conveniently runs through my entire house to any place I would want to connect a device, so it would be easiest to have a Raspberry Pi (or similar) run off the 29V supply voltage and directly connect to the KNX bus to read and write signals.

On the Raspberry Pi 2 and 3 you need to disable the serial console. Edit /boot/cmdline.txt and remove the console=ttyAMA0 entry. Then reboot. On the Raspberry Pi 3, the serial console is on ttyAMA1 by default. However, that is a software-driven serial port - the single hardware serial interface is used for Bluetooth on the Pi3. IC00R01KNX RaspBerry PI® KNX Interface is the best solution to connect your Raspberry application into the Home and Building Automation world. This easy to use board can be intend as a gateway developed with a simple serial protocol to receive and send telegrams on the KNX Bus. The on board micro controller includes the KNX Stack required to interact with the KNX Bus. After installing the KNX addon, you can instantiate a KNX/IP Gateway in the Things tab under Configuration. As KNXD and OpenHAB are running on the same Raspberry Pi, the Network Address is just the local host 127.0.0.1. If you run both on a different system, the Network Address has to be the one of the system running KNXD. integration for Raspberry Pi and other platforms. Kempten/Germany, March 2019: KNX can now be used via software in CODESYS-based building controllers such as Raspberry Pi, BeagleBone® or IoT2000. In industrial automation, CODESYS is the market-leading, manufacturer-independent development system according to the international standard IEC 61131-3.

The eibd daemon has minimal hardware requirements. There are two possibilities for connecting a computer to the EIB/KNX Bus over a RS232 serial interface. Both are supported by eibd. Hi, in my previous posts EIB/KNX Router with an USB Interface and KNX/EIB Router with a TPUART module I described how to use a Raspberry PI as EIB/KNX Router with eibd. eibd is no longer in development so I decided to give knxd, a fork of eibd, a try:-) The script attached at the end of the post is written for raspbian but should also work an all debian system with systemd imit system..
You can't connect the KNX bus to anything on the pi. The KNX bus has its own electrical specs, and you need specialized hardware to connect to it. Such hardware is available, but probably a KNXnet/IP device (such as the Siemens N148) is a better option. 1. root@raspberry~: # bcuaddrtab usb:1:4:1:0:0. If not a size of 0 is reported, means that telegrams are filtered, clear the address table size to receive everything from the bus. Specify only the first two digits of the USB Bus address! 1. root@raspberry~: # bcuaddrtab -w 0 usb:1:4. reboot your the PI.
KNX/EIB Gateway with Raspberry PI
KNX Hat provides 2 external connectors: - DC 12-24V up to 2A Input for powering the raspberry Pi. - KNX/EIB Twisted Pair Bus connector. The Raspberry Pi MUST NOT be powered by 2 external sources at the same time, for example, USB and external DC 12-24V input. Before installation: Select the correct UART pins by positioning both jumpers either. The KNX BAOS Module 838 kBerry is an adaptation of the proven KNX BAOS modules specifically made for the Raspberry Pi. It can be attached directly to the pins of the Raspberry Pi and communicates via a serial port galvanically isolated. The module includes a certified KNX stack and can be configured with the ETS.
